Abstract (en)
The present invention relates to the field of low-voltage electric appliances, and more particularly to a moving contact mechanism. A contact support of the moving contact mechanism is disposed to rotate around a third axis, a moving contact is pivotally disposed around a contact axis, and both ends of the contact spring are a third end of the spring and a fourth end of the spring, respectively, which are rotatably connected to the moving contact and the contact support respectively. A geometric axis of the contact spring is a second axis line. The second axis line is located on one side of the third axis when the moving contact is normally switched on or off, and the contact spring keeps the moving contact in a normally switched-on position or a normally switched-off position. The moving contact rotates relative to the contact support when the moving contact is repelled by an electric repulsion force generated by a short-circuit current; and the moving contact drives the contact spring to rotate around the fourth end of the spring, so that the second axis line swings to the other side of the third axis, and the moving contact remains in a temporary breaking position. The moving contact mechanism of the present invention has a simple structure, and the contact spring can achieve the locking of the moving contact.
